Distributed active element in 10 Gbps network
Petr Holub, Eva Hladká · 2007
In this paper, we propose a distributed Active Element for tightly coupled cluster environment, suitable for distribution of large bandwidth data that exceed capacity of every single node in the cluster. This approach utilizes the fact that real-time multimedia transmission systems relying on non- guaranteed protocols like UDP need to handle limited packet reordering on their own. We describe the Fast Circulating Token protocol, which enables imposing even stricter bound on the outbound packet reordering. The whole system is examined on 10 GE testbed and shows very good performance. The FCT provides expected improvement, making the packet reordering comparable to long haul networks.
